A common access card (CAC) is a Unites States Department of Defense (DoD) smart card for multifactor authentication. CACs are issued as standard identification for active-duty military personnel, reserve personnel, civilian employees, non-DoD government employees, state employees of the National Guard and eligible contractor personnel.
It also serves as an identification card under the Geneva Conventions (esp. the Third Geneva Convention). In combination with pin, a CAC satisfies the requirement for two-factor authentication: something the user knows combined with something the user has.
